I am naked at home generally. I wear Bike Jockstraps, the newer ones with the narrower waist band. I get sore and uncomfortable without support. At home, it's easy to stay in control. I also, through a friend, found Tiger Briefs from TIGERUNDERWEARSTORE.COM.
Old fashioned, full rise briefs with a double seat in the back through to the front. Once stretched out, they are roomy and comfy, but be aware, these are BIG BRIEFS. If you enjoy smaller things, they aren't for you. If you shoot for comfort, then this is the way to go.
Also, for hung guys, if you need a cup....Nutty Buddy is the only way to go. All my junk drops right in and I don't feel it when I run with it on nor does it make my look like a freak, which others have done. Check out the videos on the site, hilarious.
